Abstract
The present invention provides a method for determining the spacing and size of air guns in a tuned air gun array. Volume ratios are calculated based upon a predetermined maximum volume for any individual air gun. The volumes are cross-referenced to spacings for optimum air gun interaction. The resulting air gun array operates as a broadband high-energy point source.
Claims3
A method of selecting volume ratios of air guns spaced apart in a seismic exploration array comprising the steps of:
- selecting the largest individual volume of the desired array;
- selecting the total number of air guns in the array;
- determining the volume ratio for individual guns according to the equation ##EQU14## where N=said number of volumes
- Vr=the volume ratio corresponding to the index n
- n=1, . . . N-1
- Vro<8=largest volume ratio ##EQU15## P=parameter>0.76.
